why the ground around the fountain should suffer from drought ? the game would be even more competitive with the conquest of the fountain for more resources.

Right now rouge is almost useless. Can we improve them with trap and mine abilty? While walking, rouge will randomly deploy trap that will drain half of enemy's minion HP when stepping on it. It will be fun and enrich the castle gameplay so the new player can kill others by creating rogue. 

In castle mode add some barbarian castles on the edges of the map that contain small corn fields and stacks of wood 

I've noticed often enemies are able to go through other team's gates. Anyone else experience this?

It's hard to aim catapult on moving targets, and when I did hit it did hardly any damage. Also make the range easier to see with a shaded region or the catapult crosshair doesn't go any farther than the range.

When I leave my units at nearest field, often times they will wonder far away from that field, like they are chasing something; Sometimes other players, and sometimes just random places. 

Otherwise great Game.

You don't even have to make the sound effects! Just make notes come out of them once you click them and they start playing. Also add an icon to the units being boosted. Drums could boost up attack stats, Trumpets could boost the speed, Violins could boost the block chance, and Flutes could boost the health.

Me and my friends cannot play together on the same server :(

Similar to in Total War games, you could have a card at the bottom of the screen for each villager in your party. This would make it easier to keep track of their health and to apply helmets/weapons/shields to them in the heat of battle
